An oil pump is usually located in the oil pan. If you want to change the oil pump and replace it with a new one, roll up your sleeves and get ready for some dirty work.

Remove the mounting bolts for the oil pump with a socket wrench. Detach the oil pump and its gasket from the engine.

Clean the mounting surfaces for the oil pump with a shop towel. Mount a new gasket to the new oil pump. Install the oil pump to the engine and tighten its mounting bolts to 80 inch-lbs. with a torque wrench.

Install the sprocket for the crankshaft and the timing chain with a socket wrench. Connect the cable for the negative battery terminal.

Fill the engine with oil and start the vehicle. Check and repair any oil leaks.

Drive your Toyota Tacoma up onto ramps or lifts so you have room to work as you pull out the oil pump. You could also use a jack, but make sure you brace the front wheels so they don't roll. In addition, set the emergency break firmly into position so the car doesn't roll.

Relieve the fuel system pressure and then disconnect the negative and positive battery cables and remove the battery. Drain the engine coolant as well as the engine oil. Take the engine out of the vehicle and safely store it in a suitable holding device.

Remove the oil level gauge guide, the water inlet, the belt tensioner, the idler pulley No. 2 sub assembly, the idler pulley No. 1 sub assembly, the crankshaft pulley, the lower oil pan, the strainer and pickup tube, the upper oil pan, the ignition coil assembly, the cylinder head cover, the camshaft timing oil control valve assembly, the VVT sensor, the oil filter bracket sub assembly, the timing chain case cover retaining bolts, the cover from the engine, the O-ring from the left cylinder head, the three bolts, the oil pipe, the two O-rings, the seven oil pump cover bolts, the gears from the timing chain case cover and the oil pump relief valve.

Cover your new oil pump relief valve with fresh engine oil to lubricate it. Install the plug, using a new gasket and torque it to 36 ft-lb.

Coat the oil pump gears with clean engine oil also. Line up these gears in the timing chain case cover with the identification marks facing oil pump cover side. Insert the cover. Take turns tightening each bolt in order, torquing them to 80 in-lb. Add the oil pipe and tighten the bolts to 80 in-lb.

Put in a new front case oil seal then insert a new O-ring onto the left cylinder head. Apply continuous beads of seal packing (0.12 to 0.16 inches in diameter) using part number 08826-00080 on all the parts except the water pump. Add the timing chain case cover bolts, tightening the bolts and the nuts by taking turns until they reach 17 ft-lb.

Re-install the engine. Add fresh engine coolant and engine oil. Start your engine and check your working area for leaks.

Drain the oil out of your engine and disconnect the negative battery cable. Remove the fender apron seal and the undercover, the front exhaust pipe, and the front exhaust pipe bracket from the No. 1 oil pan.

Remove the following components in order: the alternator drive belt, the air conditioner compressor, the power steering pump drive belt and the adjusting strut, the timing belt along with the belt pulleys, the rear timing belt cover, the air conditioning compressor housing bracket, the No. 2 oil pan and oil strainer, as well as the No. 1 oil pan and baffle plate.

Disconnect the crankshaft position sensor and remove all nine of the oil pump bolts. Remember where each bolt was located.

Take out the oil pump body by reaching in and grasping between the oil pump and main bearing cap. Remove the O-ring from the cylinder block then remove the plug, gasket, spring and relief valve from the oil pump body.

Finish by taking out all nine screws, the pump body cover and the driven rotors. Clean all components to remove contaminants.

Install the Oil Pump

Install the new oil pump by slipping it into the same spot where the old one was. Reconnect the following: the driven rotors, the drive pump body cover, all nine screws, the oil pump relief valve, the spring, the gasket and the plug to the oil pump body.

Insert a new O-ring onto the cylinder block and add liquid sealant to the oil pump and the engine block. Put the oil pump back on the engine block.

Add and tighten the bolts over several passes, keeping the torque even. The 10 mm head should be 69 in-lb. and the 12 mm head should be 14 ft-lb.

Reconnect the crankshaft position sensor, torquing the bolt to 69 in-lb. Insert the No. 1 oil pan and oil strainer and the No. 2 oil pan.

Reinstall the air conditioner compressor housing bracket, tightening the bolts to 18 ft-lb. Add the rear timing belt cover, tightening those bolts to 74 in-lb. Insert the timing belt pulleys, the timing belt and the adjusting strut and power steering drive belt, tightening those bolts and the nut to 32 ft-lb.

Install the air conditioning compressor, the alternator drive belt and the front exhaust pipe bracket to the No. 1 oil pan, torquing the bolts to 15 ft-lb. Add the front exhaust pipe, the undercover, and the right fender apron seal.

Connect the negative battery cable and fill the engine with fresh oil. Start your Toyota Camry and look for leaks in your working area.
